Description

Technical Field

[0001] The utility model relates to the technical field of anchoring and connecting photovoltaic cables, in particular to a double anchoring structure of photovoltaic cables. Background Art

[0002] Photovoltaic brackets are structures used to support solar panels in solar photovoltaic power generation systems. With the further development of solar photovoltaic power generation technology, photovoltaic power generation projects in complex environments such as mountains, water surfaces, Gobi, deserts, and bays have gradually been carried out. In terms of the selection of photovoltaic brackets, rigid brackets are difficult to apply to complex geographical conditions due to their limitations such as non-adjustability after fixation, poor wind resistance, and weak corrosion resistance. The flexible prestressed bracket using steel strand cables has been increasingly used in projects in complex terrain areas because it can better improve the support method of photovoltaic power generation systems with large spans, has high environmental space utilization, and low cost. In this application, a common anchoring form of photovoltaic cables is to use the friction between the clip and the steel strand bundle, and wedge the conical clip into the working anchor plate through the retraction of the steel strand bundle. The tapered clip and the working anchor plate are used to make the clip produce a large bite force and clamping force on the steel strand under the action of tension to achieve the anchoring of the steel strand bundle. After the extrusion is completed, the cover plate is screwed on. Such anchoring method can only form one layer of anchoring structure, and the current flexible method to prevent the loosening of the clip and compensate is either to thicken the cover plate and open a hole to accommodate the inner spring, or to thicken the anchor plate and expand its anchor hole to accommodate the inner spring. Such flexible compensation methods require the manufacture of specific anchors, and the processing procedures are complicated and costly. Utility Model Content

[0003] The utility model aims to provide a photovoltaic cable double anchoring structure, which can solve the problems of complex processing procedures and high costs in existing flexible compensation methods.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: the double anchoring structure of the photovoltaic cable includes a steel strand and a bracket installed on the steel strand, a photovoltaic anchor is installed on the steel strand on one side of the bracket, a clip wrapped around the steel strand is extruded inside the photovoltaic anchor, a steel strand connector is mounted on the steel strand outside the large end of the clip, and the steel strand connector is a columnar body, which is provided with a long through hole adapted to the steel strand, and an external thread is provided on the outside, and a locking nut is externally threaded on the end adjacent to the clip.

[0005] In the technical solution of the above-mentioned photovoltaic cable double anchoring structure, a more specific technical solution may also be: the external thread of the steel strand connector is arranged on the outer wall of the end adjacent to the clip.

[0006] Furthermore, a disc spring is provided between the steel strand connector and the large end of the clip.

[0007] Furthermore, an anti-loosening cover is provided between the steel strand connector and the large end of the clip, the anti-loosening cover is provided with an internal thread, the photovoltaic anchor has an external thread corresponding to the anti-loosening cover, and the anti-loosening cover is threadedly connected to the photovoltaic anchor.

[0008] Furthermore, the end of the photovoltaic anchor on which the small end of the clip is mounted is crimped to the bracket.

[0009] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0010] 1. Simple structure and low cost: A steel strand connector is mounted on the large end of the clip, and the steel strand connector is a columnar body, which is provided with a long through hole adapted to the steel strand and an external thread. The steel strand connector has a simple structure, a simple processing procedure and a low cost. After extrusion and matching with a locking nut, the clip and the anchor can be locked without ordering a special anchor, and production and processing are convenient. Moreover, when the clip fails for some reason, the steel strand connector can also be subjected to tension, thereby playing a role of double anchoring.

[0011] 2. Convenient construction and easy operation, and can be constructed without special equipment; a disc spring or anti-loosening cover is provided behind the clip to tighten with a locking nut, which has a good anti-loosening effect; the locking nut used is a standard part with wide versatility.

[0015] In order to make the above-mentioned purposes, features and advantages of the utility model easier to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. In the following description, many specific details are set forth in order to fully understand the utility model, but the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0016] In the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] like Figure 1 The double anchoring structure of the photovoltaic cable of the present embodiment 1 shown includes a steel strand 7 and a bracket 6 installed on the steel strand, and a photovoltaic anchor 5 is installed on the steel strand on one side of the bracket, and a clip 4 wrapped around the steel strand 7 is extruded inside the photovoltaic anchor, and a steel strand connector 1 is mounted on the steel strand 7 outside the large end of the clip 4. The steel strand connector is a columnar body, which has a long through hole adapted to the steel strand inside and an external thread outside. A locking nut 2 is externally threaded on the end adjacent to the clip 4, and the external thread of the steel strand connector 1 is opened on the outer wall section of the middle part of the steel strand connector from the end adjacent to the clip 4; a disc spring 8 is crimped between the steel strand connector 1 and the large end of the clip 4, and the disc spring 8 is tightly attached to the large end of the clip and the locking nut, and has a good anti-loosening effect; the end of the photovoltaic anchor where the small end of the clip is installed is crimped to the bracket.

[0018] like Figure 2 The photovoltaic cable double anchoring structure of the embodiment 2 shown in the figure has no disc spring 8. An anti-loosening cover 3 is installed in the place of the disc spring 8. The anti-loosening cover has an internal thread. The photovoltaic anchor 9 of the embodiment has an external thread corresponding to the internal thread of the anti-loosening cover 3 on its outer wall. The anti-loosening cover 3 is threadedly connected to the photovoltaic anchor 9. The external thread of the steel strand connector of the embodiment is opened on the outer wall section extending from the end adjacent to the clip 4 to a quarter of the steel strand connector.

[0019] The installation process of this anchoring structure is as follows: after the steel strand passes through the bracket, first install the photovoltaic anchor and the clip, and after the tensioning is completed, install the anti-loosening cover 3 or the disc spring 8, and use an extruder to cold extrude the steel strand connector. After the extrusion is completed, tighten the locking nut to prevent the clip from withdrawing, which plays a role in preventing loosening. When the clip fails for some reason, the rear steel strand connector can still be subjected to tension, which plays a role of double anchoring.
